DIVERS HELMET.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed July 27,1907. Serial No- 385,870.

To all whom it may concern:

Be it known that I, PETER HANSEN, a citizen of the Kingdom of Denmark, and a resident of Copenhagen, Denmark, Toldbodgade 11, diver, have invented new and useful Improvements in Divers Helmets, of which the following is a specification.

The invention applies to a divers helmet, which is lighter and quicker to buckle on than those hitherto known. I

The invention is shown on the drawing, where Fig ure 1 shows the helmet in side view; Fig. 2 shows the same in front View; Fig. 3 the ring.

The divers helmet or hat has the usual form and is as generally known fitted with glass panes as also with a cock and an airhole. The hathas hitherto been fixed on by placing the collar of the divers dress on the topof the edge of the helmet, whereupon again on the top of the collar, iron bands were placed, which were held in place by nuts, screwed on bolts at the edge of the helmet. This arrangement is defective thereby,

that the iron bands must needs be parted in two or more pieces, inasmuch as an iron band of one piece will not be placeable down over the helmet, and as each such iron band according to its size must be fastened by means of two or more nuts, it is rather timewasting work to put the hat on and off, particularly so, if at the same time crests on the dress are to be placed into grooves on the iron bands. As contradistinguish ed therefrom, the plan of the present invention is to provide the hat with two holes corresponding to bolts (1 on a ring I), which, before the helmet be put on, is placed below the collar 0, the latter having a thickened edge. As the ring I) is in one piece (continuous), it is suflicient to have two bolts, so that by this means a very considerable saving of time is effected, while at the same time a completely reliable tightening is se cured.

What I claim, and desire to secure by Letters Patent is:

Adivers helmet, characterized by a loose ring with two screw bolts said ring being placed under the collar of the divers dress and screwed on to the hat.

Signed by me at Copenhagen, Denmark this 15th day of July 1907.

PETER HANSEN.
